Robin Roberts on Monday appeared on "Good Morning America" and made a big announcement regarding her health.

"I'm so happy to be sharing this news with everybody," said Roberts. "[My] last bone marrow test showed no abnormalities. The majority of the marrow is my sister's and it is healthy. Praise God. What all this means, my doctors are waiting for this information to be able to tell me that I can be in the process of returning to the anchor chair."

Roberts said she hopes to return sometime in February, but she did not specify a date.

The 52-year-old has remained in good spirits since undergoing rigorous chemotherapy treatments and a bone marrow transplant to treat myelodysplastic syndrome, a rare blood and bone marrow disease.

Roberts revealed her MDS diagnosis in June and has been on medical leave from "Good Morning America" since the end of August. Roberts received a bone marrow transplant from her sister, Sally, in September.
